Job description

Join us in building the future of finance.

Our mission is to democratize finance for all. An estimated $124 trillion of assets will be inherited by younger generations in the next two decades. The largest transfer of wealth in human history. If you're ready to be at the epicenter of this historic cultural and financial shift, keep reading.

About the team + role

We are building an elite team, applying frontier technologies to the world's biggest financial problems. We're looking for bold thinkers. Sharp problem-solvers. Builders who are wired to make an impact. the company isn't a place for complacency, it's where ambitious people do the best work of their careers. We're a high-performing, fast-moving team with ethics at the center of everything we do. Expectations are high, and so are the rewards.

The Developer Infrastructure org is the engine behind the company's entire engineering organization - a collection of tightly integrated teams whose collective mission is to make every engineer at the company faster, more reliable, and exponentially more productive. The org spans four major teams: DevX (Developer Experience), TestX (Test Infrastructure), Backend Platform, and Mobile Platform. DevX owns the company's monorepo and Bazel-based build infrastructure - the critical layer between a developer writing code and that code being ready to ship - along with the company's full CI/CD pipeline and remote build execution cluster. TestX owns the infrastructure behind the company's entire test experience: the integration test environments, and personal development environments that serve as miniature simulations of the full the company system, giving engineers a safe, isolated space to test their code end-to-end before it ever touches production. Backend Platform and Mobile Platform own the core language runtimes, libraries, IDEs, and developer toolchains across Python, Go, TypeScript, Swift, and Android. Together, these teams share a single north star: leveraging AI and agentic systems to fundamentally transform the company's software development lifecycle - making every engineer dramatically more productive and the entire org a force multiplier for the business.

As the Senior Staff Software Developer, Developer Infrastructure, you are the technical driver of this entire org - the Uber Tech Lead unifying DevX, TestX, Backend Platform, and Mobile Platform under one cohesive technical vision. Your primary focus will be DevX, owning the technical direction of the company's most critical build and developer infrastructure. But your influence stretches far wider: you will be a driving force in weaving AI and agentic development deeply into every layer of the software development lifecycle - from intelligent code review and automated build pipelines to agentic coding systems that multiply what each engineer can ship. This is a rare opportunity to shape not just how the company builds software today, but what engineering velocity looks like for the entire industry!

This role is based in our Toronto office, with in-person attendance expected at least 3 days per week.

At the company, we believe in the power of in-person work to accelerate progress, spark innovation, and strengthen community. Our office experience is intentional, energizing, and designed to fully support high-performing teams.

What you’ll do

• Own the technical direction and roadmap for the Developer Infrastructure org - serving as the Uber Tech Lead across DevX, TestX, Backend Platform, and Mobile Platform, unifying four engineering teams under a shared technical vision

• Lead and evolve the company's Bazel-based monorepo build infrastructure - own the remote build execution cluster, drive language-agnostic build optimization across Python, Go, TypeScript, and more, and ensure fast, stable feedback loops for the entire engineering org

• Scale CI/CD pipelines to support thousands of daily builds with speed, safety, and reliability - overseeing GitHub repository configurations, pre-merge checks, and test execution infrastructure across the company

• Drive the vision for TestX - the test infrastructure and environments that power the company's entire test experience, including integration test environments and personal development environments that simulate the full the company system so engineers can test safely and confidently

• Champion the integration of AI and agentic systems across the full software development lifecycle - driving initiatives that use intelligent automation and coding agents to multiply developer velocity, improve code quality, and accelerate the pace of innovation across the org

• Set technical standards across Backend Platform and Mobile Platform - owning the vision for core language runtimes, libraries, IDE tooling, and developer environment security across Python, Go, TypeScript, Swift, and Android

• Partner with engineering leadership and cross-functional stakeholders to define and execute a long-term developer infrastructure roadmap that embeds AI as a force multiplier at every layer of the SDLC

What you bring

• 10+ years of software engineering experience with a demonstrated track record at the Senior Staff, Principal, or Distinguished Engineer level - you've set technical direction at the org or company level, not just the team level

• Deep expertise with Bazel and large-scale monorepo build systems - you've owned remote build execution infrastructure at scale and understand the architectural tradeoffs deeply

• Experience building and operating CI/CD pipelines at massive scale - across thousands of daily builds, multiple programming languages, and complex pre-merge pipeline logic

• Fluency in Go and/or Python; broad familiarity with TypeScript, Swift, or Android development environments is a strong signal

• Strong background with distributed systems, Kubernetes, and cloud infrastructure (AWS preferred) - you understand the full stack of developer tooling from IDE to deployment

• Experience with test infrastructure, integration test environments, or developer environment platforms - you understand what a great test experience looks like at scale

• Genuine interest in or hands-on experience with agentic AI systems, automated code review, or AI-driven developer velocity programs - you have a clear point of view on how AI will reshape the software development lifecycle and want to be the one building it

• Exceptional technical leadership, communication, and influence skills - you've unified cross-functional engineering teams around a shared vision and driven ambiguous, org-spanning initiatives to completion

• Track record of mentoring senior engineers and elevating the technical bar across large, diverse engineering organizations

What we offer

• Challenging, high-impact work to grow your career

• Performance driven compensation with multipliers for outsized impact, bonus programs, and equity ownership

• Top tier benefits to fuel your work, including supplemental health insurance, ancillary insurance, and mental health support programs

• Access to the best AI tools on the market and continuous AI skill-building for every employee, technical or not

• Lifestyle wallet - a highly flexible employer-paid benefits spending account expenses beyond traditional benefits such as wellness, childcare, learning, and more.

• Time off to recharge including company holidays, paid time off, sick time, paid volunteer time off, parental leave, and more!
